DAVIS SHEEN, OF RUDD, TEXAS.

WINDMILL AND ENGINE COUPLING.

Application filed June 26, 1911.

T 0 all whom it may concern:

Be it known that I, DAVIS SHEEN, a citizen of the United States, residing at Rudd, in the county.of Schleicher and State of Texas, have invented a new and useful Vindmill and Engine Coupling, of which the following is a specification.

The invention relates to a coupling for connecting the piston or plunger of a pump with either a windmill or 'an engine, or analogous motor.

The object of the present invention is to improve the construction of couplings, and to provide a simple, eflicient and comparatively inexpensive windmill and engine coupling, adapted to be easily operated to connect the piston or plunger of a pump with either the pitman of an engine, or the pump rod of a windmill.

lVith these and other objects in view, the invention consists in the construction and novel combination of parts hereinafter fully described, illustrated in' the accompanying-drawing, and pointed out in the claims hereto appended; it being understood that various changes in the form, proportion, size and minor details of construction, within the scope of the claims, may be resorted to without departing from the spirit or sacrificing any of the advantages of the invention.

In the drawing :Figure 1 is a side elevation of a coupling, constructed in accordance with this invention, a portion of the tower of the windmill and the well being in section. Fig. 2 is an enlarged vertical sectional view of the coupling. Fig. 3 is a similar view on the line 38 of Fig. 2. Fig. 4 is a horizontal sectional view on the line 44 of Fig. 2. Fig. 5 is a similar view on the line 5-5 of Fig. 2. Fig. 6 is a horizontal sectional View on the line 66 of Fig. 2.

Like numerals of reference designate corresponding parts in all the figures of the drawing.

In the accompanying drawing in which is illustrated the preferred embodiment of the invention, 1 designates an upright casing composed of side plates spaced apart by a central vertical bar or piece 2, which cooperates with the side plates to form opposite guides or ways 3 for the reception of vertically reciprocatable bars 4 and 5, which are retained in the grooves or ways 3 by means of an approximately U-shaped cuff 6. The cufi 6 is composed of opposite sides and Specification of Letters Patent.

a connecting portion, the sides being arranged at the side edges of the plates of the casing and extending across the grooves or ways thereof, as clearly shown in Figs. 3 and 5 of the drawing. The outer terminals of the sides of the cuff project beyond the casing and are connected by a bolt 7. The casing instead of being made of separate pieces may be, of course, constructed in any other desired manner. The spaced side plates of the casing are secured to the centrally arranged spacing bar or piece 2 by means of lower bolts 8, which also attach the casing to the upper end of the piston or plunger 9 of a pump 10." The pump 10 may be of any preferred construction, and the cuff 6 is secured to the casing by upper horizontal bolts 11 and 12, which also connect the side plates of the casing. The bolt 12 pierces the upper end of the spacing bar or piece 2, which terminates short of the upper ends of the side plates of the casing to provide a recess 13 for the reception of the lower portions of approximately triangular plates or members 14, which are pivoted in the recess 13 by the bolt 11. The oscillatory plates or members 14, which taper downwardly, as clearly illustrated in Figs. 1 and 2 of the drawing, form an oscillatory sup port for a pair of opposite catches 15 and 16 for connecting the casing with either of the reciprocatory bars 4 and 5. Each catch consists of a pair of parallel sides or links 17, connected at their inner ends with the plates 14 by an inner pivot 18 and having their outer ends connected by an outer transverse pin 19. The reciprocatory bars 4 and 5, which pass through the catches, as clearly illustrated in Fig. 5 of the drawing, are each provided with inner and outer notches 20 and 21, arranged at different elevations and adapted to be engaged by the catches when the same are in an inclined position, as illustrated in Figs. 1 and 2 of the drawing. The inner pivot pins 18, which are located opposite the lower notches or recesses 20, operate in the space between the vertically reciprocatable bars 4 and 5, and the plates 14 are located at the side faces of the same. The inner or lower notch or recess 20 has upper and lower approximately horizontal walls, and the upper notch 21 has a lower approximately horizontal wall and an upper inclined wall 22. The inner pin 18 is engaged by the upper wall of the lower notch or recess of its co-acting reciprocatable bar on the down stroke, and the lower wall of the upper notch or recess of such bar engages the outer pin of the catch on the up stroke.

When the outer pin or engaging portion of the catch 15 is swung into the notch or recess 21 of the reciprocatable bar 4, the latter in its upward movement will lift the catch 15 and draw the inner pivot thereof into the inner recess or notch 20. This movement oscillates the supporting plates 14 and withdraws the inner pivot of the other catch 16 from the lower inner notch or recess of the reciprocatable bar 5. The lifting movement of the catch 15 draws the casing in the direction of the actuating bar 4 and there is comparatively little friction in the operation of the coupling. When the outer pin or engaging portion of the catch 16 is swung into the upper notch of the reciprocatable bar 5, the latter in its upward movement will draw the inner pin or pivotof the catch 16 into the lower inner notch of the recess 20 of the bar 5, and withdraw the pivot of the other catch from the lower notch or recess 20 of the bar 4, and the continued upward movement of the bar 5 will cause the catch 15 to swing outwardly and downwardly by gravity and clear itself automatically of its engagement with the bar .4. When the catch swings outwardly and downwardly it rests upon the upper edge of the cuff, and the outer engaging portion or pin lies beyond the co-acting reciprocatory bar, and there is no liability of the catch becoming accidentally engaged with the same.

The vertically reciprocatable bar 4 is de signed to be connected at its upper end with the pump rod of a windmill and to be actuated by the same, or it may constitute a portion of the pump rod, and it preferably passes through an opening 23 in a horizontal guide bar 24, suitably secured at its ends to the tower 25 of the windmill, and equipped with approximately L-shaped metallic plates 26, having spaced projecting flanges receiving the bar 4 between them and forming wear plates for protecting the bar 24. When the catch 15 of the coupling is engaged with the bar 4, the piston rod or plunger 9 of the pump will be actuated by the windmill. The windmill actuated bar 4 also passes through a guide consisting of spaced plates or pieces 27, secured by bolts 28, or other suitable fastening devices to the opposite faces of the upper end of the reciprocatory bar 5. The sides or plates 27 of the guide are spaced apart by the upper end of the bar 5, and they extend in opposite directions therefrom, and they are also connected by a central horizontal bolt 29, upon -which an anti-friction roller 30 is mounted.

The anti-friction roller is arranged in the space between the bars 4 and 5, and it is adapted to bear against the latter when the nected at its lower end with a crank or wrist pin 34 of an engine 35 or analogous motor, and its upper end 36 is bifurcated or forked to straddle the projecting terminals 31 of the sides or plates 27 of the guide, a spacing sleeve 37 being preferably mounted on the bolt 32 and interposed between the projecting ends 31. The engine is adapted to actuate the pump and is designed for use during the summer season and at other times when there is comparatively little wind. At other seasons when there is ample wind for operating the pump through the windmill and there is no occasion for frequently coupling the pump rod from one of the bars 4 and 5 to the other, the pitman may be disconnected from the guide, and the plates 27 of the latter may be secured to the bar 4 by means of a bolt or pin, suitable perforations 38 and 39 in the bar 4 and the plates 27 being provided for this purpose. This will cause the bars 4 and 5 to move in unison and will relieve the coupling of wear. However, at seasons of the year where it is desirable to use the coupling frequently to change the power, the pitman of the engine will be pivoted to the plates 27 and the change will be effected by means of the catches of the coupling.

Although a straight pitman connection between the plates 27 and the engine is illustrated in the accompanying drawing, it will be readily understood that any suitable means may be employed for transmitting motion from the engine or other motor to the reciprocatory bar 5.

Having thus fully described my invention, what I claim as new and desire to secure by Letters Patent, is

1. A device of the class described including a casing designed to be connected with the plunger or piston rod of a pump, recip-' rocatory bars slidably arranged in the casing, one of the bars being provided with means for connecting it with the pump rod of a windmill, means for connecting the other bar with an engine or motor, a guide spaced from the casing and mounted on one of the. reciprocatory bars and receiving the other reciprocatory bar and provided with an antifrict-ion device arranged to bear windmill, a guide spaced from the casing and secured to the other reciprocatory bar and slidably receiving the first-mentioned reciprocatory bar, a pitman pivoted to the guide and adapted to be connected with the crank or wrist pin of an engine, and means for connecting either of the reciprocatory bars with the casing.
